Founding Purpose Principles Membership Path Next Era

Founding Purpose

Delta Sig was founded 125 years ago, on the belief that men of different regligious backgrounds could not only coexist, but grow with and learn from one another. Since 1899, our fraternity has unified thousands of members committed to improving themselves, their families, communities, countries and world in a positive way.

Core Principles

Building on years of rich tradition and learned experience, Delta Sig continues to value the same core principles that our founders believed in. Learn about our fraternity’s commitment to fostering culture, harmony and friendship.

Membership Journey

Over time, the member experience offered by Delta Sig has continued to evolve, with our founding principles as a consistent guiding light. Our members join a path taken by thousands of men, all making the most of three distinct phases.

The journey begins with an introductory New Member phase. This is the starting point for all of our members, as they get to know the other men in their chapter, discover the fraternity's rich history, explore the resources and leadership opportunities we offer, and learn to thrive in a fraternal atmosphere.

Highlights for New Members include:

  • A six-week educational period, led by chapter officers

  • Mentorship program with an older member of the chapter

  • Guest speakers who have helpful insight to share

  • Introductory leadership programs at the national level

For the majority of their undergraduate years, our members are Initiated Members. This stage typically begins about halfway through a New Member's first term, culminating toward an enlightening initiation that grants full, lifelong membership in the fraternity.

Initiated members gain access to many new opportunities, such as:

  • Eligible to run for office within the chapter

  • Apply for flagship leadership programs at the national level

  • Attend our biennial national convention

  • Voting on chapter and national-level affairs

Membership in Delta Sigma Phi is for life, meaning our Alumni Members continue to reap the benefits of fraternity well after graduation. Once a member becomes an alumnus of their college or university, they also become an alumnus of Delta Sigma Phi.

At this stage, and for the rest of their lives, members enjoy many benefits:

  • Join their fellow chapter alumni in the local Alumni Chapter

  • Connect with other Delta Sigs via regional Alumni Associations

  • Attend our biennial national convention, potentially as a voting delegate

  • Volunteer as a chapter advisor, commissioner, facilitator or board member

  • Give back to the Delta Sigma Phi Foundation to ensure success for the next generation

Our Next Era

Guided by our founding principles, Delta Sigma Phi has consistently redefined the concept of fraternity for more than 125 years. At our 2025 Convention, we unveiled our vision and strategy for the future of Delta Sigma Phi—our Next Era.

As Delta Sig enters the Next Era, we're committed to becoming the best version of ourselves through a bold new vision—a vision that honors and expands on our commitments to the welfare of men, the bulwarks of democracy, and our nation’s school systems.

Over the next decade, we invite our members, and anyone who cares about the future of men in our country, to join us as we refocus and accelerate our work. Together, we will leverage our shared bonds, our unwavering belief in the power of fraternity, and our unique place in society, to live up to our promise and our potential.

We are incredibly thankful to the hundreds of voices who provided feedback and helped bring this vision to life. Collectively, we are eager to launch the Next Era of Delta Sigma Phi.
